Find all CSS files on website using PHP

Question

As the title suggest i am trying to find all CSS files on a website (for later use i will find all image urls in each of the CSS files on the server).

Now ive tried the following:

    $url_to_test = $_GET['url'];
$file = file_get_contents($url_to_test);
$doc = new DOMDocument();
$doc->loadHTML($file);
$domcss = $doc->getElementsByTagName('css');

However the array domcss turned out empty (for a site i know has alot of css files).

So my question is how do i find all css files loaded on a given page?

Uhm, im not familiar with things like that, but the "TagName" is not css. You need <link rel="stylesheet" href="your/css/file">, so ofc you get an enmty array. — Realitätsverlust

May I ask what your use case is? It sounds like there may be a simpler solution to the problem. — superluminary

I have a javascript that calls a function that quickly will get all images of the site and returns it as a json — Marc Rasmussen

you should check for link not css, change:

$domcss = $doc->getElementsByTagName('css');

to

$domcss = $doc->getElementsByTagName('link');
foreach($domcss as $links) {
    if( strtolower($links->getAttribute('rel')) == "stylesheet" ) {
       echo "This is:". $links->getAttribute('href') ."<br />";
    }
}

Try this:

preg_match('/<link rel="stylesheet" href="(.*?)" type="text\/css">/',$data,$output_array);

kovach Over a year ago

data is your data you grabbed, with curl or any other way. And output is an array of css files..

Okay. The following returns an empty array: $file = file_get_contents('as.com/'); preg_match('/<link rel="stylesheet" href="(.*?)" type="text\/css">/', $file, $matches);
